This is interesting data

Almost every cohort is below 2. Replacement level is 2.1.

Fertility vs income of female Fertility vs age of female Fertility vs marital status Fertility vs religion Fertility vs ethnicity

Long story short is that too many white women are single and childless and the married ones are having one child only. Family trees 🌲 are upside down 🙃
